explore-unfamiliar-target

explore-unfamiliar-target is a skill for Claude Code, Codex from understudy-ai/understudy. It costs 16 tokens per session (281 once invoked), scanned A, original, MIT.

A guided skill for investigating an unfamiliar application or other assigned target and producing a short evidence-based brief.

In plain words
What is it for?
Use it to inspect first-run experiences and core feature paths, capture relevant screenshots, and produce findings, highlights, limitations, and a worker summary.
Why use it?
It gives exploration a defined goal, limits the amount of work, and records both useful findings and limitations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

explore-unfamiliar-target scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

explore-unfamiliar-target

Goal

Explore the unfamiliar target currently assigned to the run.

Operating Contract

  • Work from the visible app state rather than assuming a fixed flow.
  • Capture enough evidence for highlights, limitations, and a short brief.
  • Prefer user-visible value over exhaustive settings exploration.

Inputs

  • targetName
  • artifactsRootDir
  • analysisFocus

Outputs

  • findings.md
  • highlights.json
  • limitations.json
  • worker-summary.json
  • screenshots/*

Budget

  • maxMinutes=12
  • maxActions=60
  • maxScreenshots=12

Allowed Surfaces

  • Only the surfaces assigned to the run
  • Supporting workspace windows only when required

Stop Conditions

  • Enough evidence exists for 2-3 highlights and 1 limitation.
  • The budget is exhausted.
  • A hard block such as authentication or missing permissions prevents further exploration.

Decision Heuristics

  • Prefer first-run onboarding and core feature paths.
  • Capture screenshots only when they materially improve the brief.

Failure Policy

  • Escalate if payment is required.
  • Escalate if personal account creation is required.
  • Escalate if the app crashes repeatedly.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
